Motivation

You want a quick reference page of sample functions that work with dates and times.

  current-date()

Result:

  2010-05-28-05:00

Note that the "-05:00" is the offset from GMT of the server.

Current Time

  current-time()

Result:

  07:02:11.616-05:00

Current Date and Time

  current-dateTime()

Result

  2010-05-28T06:59:05.526-05:00

Note that default the letter 'T" separates the date and the time. The results after the decimal point are the number of milliseconds.
